She's probably never had an earthworm or other live food before. I'm not saying you should go that direction, but IF you did, she would probably need it cut into smaller pieces so it doesn't slap her in the face when she tries to eat it. My young Gulfie readily uses her front feet to help wrangle and subdue any food that tries to escape or fight back. She will often hold it down or pull at it with one foot while she tries to bite off a piece of a red wiggler or superworm.
poor worms ?....?
